Failed to issue COM RESET successfully after 3 attempts. Failing...
Just in case anyone else has this problem, and wants to claw their eyes out.
I upgraded the Hard Disk in my MacBook Pro about four days ago (the new MBP, summer 2009 with SD card). I installed a Hitachi Travelstar 7K320. It worked awesome for about four days, until I went to run the EFI Firmware Update this morning.
My machine stopped booting. I held Command-V to get the verbose boot output, and eventually got the message: Failed to issue COM RESET successfully after 3 attempts. Failing... - which is where the boot halted.
I removed the Hitachi and restored the stock drive, and the laptop now booted fine. I think it's something Apple will have to look into.
